What is depth and color known as in art?

In art, depth and color are often referred to as "value" and "hue," respectively. Value pertains to the lightness or darkness of a color, which helps create the illusion of depth and three-dimensionality in a composition. Hue refers to the specific color itself, encompassing the spectrum of colors visible to the human eye. Together, value and hue are essential for conveying mood, perspective, and form in artwork.
